Hi all,

For the sake of other having the same issue... It seems I have solved my problem.

I removed the engine ECU or ECM.

I openned it. There was some oxydation on some of the circuits and electrical components. I cleaned the oxydation with brake cleaner.

Then, I removed all screws holding the boards in place. It seems these screws provide some sort of grounding to the circuit board. There was a lot of oxydation there also. I cleaned this oxydation and put the screws in place.

I used some engine silicone sealant to close the ECM and make sure it will stay dry.

Since then, I do not have any starting problem anymore.
